Definitions:

Simple Squamous Epithelium

A single layer of flat cells lining surfaces involved in passive diffusion, such as the lining of blood vessels and air sacs of the lungs.

Alveoli

Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.

Alveolar Ducts

Tiny ducts in the lungs that connect the bronchioles and alveolar sacs, facilitating gas exchange.

Terminal Bronchioles

The smallest air passages in the lungs that lead to the alveolar ducts, playing a crucial role in the transfer of oxygen and carbon dioxide.
